Like my fellow mods, I love trolls - at least, some of them. Obviously, there are limits. Hate speech, spreading dangerous misinformation, porn and the like go beyond what's tolerable at any time. But a troll who just wants to stir the pot a little is fantastic fun and great for getting readership and participation levels up.
I think my favorite troll ever was on the old board, the self-righteous misogynist who will live forever in my memory as "Toothbrush Guy." I don't know if he was literally trolling in the sense of posting insincerely just to get a rise out of people, or if he really believed what he wrote. Either way it made for good troll-type posting. He insisted his wife had to be a virgin because a woman is like a toothbrush - you wouldn't want to use a toothbrush that had been in someone else's mouth, so why would you want to have sex with a woman who had been penetrated by another man.
That thread went on and on with many spirited responses from forum members, and it was hilarious. I even went back to the old place to re-read it a few times, it was so funny. Sadly, apparently the last time Paman did a forum "upgrade" they lost a large chunk of their archives, including the wisdom, or at least strenuous argumentation, of Toothbrush Guy.
My only regret about my participation in that thread is that I don't believe I pointed out to him that toothbrushes need to be replaced at regular intervals. Ah well.
